You already know that buying organic means you're going to ingest less pesticides and chemical residues than eating conventional fruits and veggies. But, now a new study suggests that organic produce may have more nutrients ...

The country of Spain consumes a lot of tomatoes, so researchers there wondered: What's healthier: organic or conventional tomatoes?

The researchers studied the polyphenol content (antioxidant content) of both types of tomatoes, and found that the organic varieties served up more antioxidants.

Why? The scientists speculate that it may have something to do with the plants' "defense mechanisms". Organically grown plants have to fight harder to stay alive, where crops sprayed with pesticides and other chemicals "can lose resistance to disease and present lower levels of nutrients, minerals and secondary metabolites."

It's a controversial topic, though, and more research is needed to determine whether these findings are true across the board. For now, though, you can feel a little better about forking over a few more pennies for organic tomatoes. I sure will!
